Abstract (en)
[origin: WO02091645A1] A method and system for demultiplexing non-intensity modulated wavelength division multiplexxed (WDM) signals includes receiving a WDM signal having a plurality of non-intensity modulated optical information signals. A plurality of the non-intensity modulated optical information signals are converted to intensity modulated signals while the plurality of non-intensity modulated optical information signals are multiplexed in at least a portion of the WDM signals.
